Abstract

A technique is described whereby a liquid crystal display (LCD) is fabricated, along with electronic circuitry, into a measuring scale ruler, so as to provide reading display versatility. Through the push of a button, the LCD displays scales in either inches or centimeters, and in various graduations, such as 1/8, 1/10, 1/15, log scale, "card scale", etc. (Image Omitted)
